Density Based Traffic Control with Remote Override
Abstract: With the burgeoning urbanization, the number of people residing in cities has been increasing since the last few decades. That implies an increase in the number of vehicles, which further leads to a calming traffic gridlock menace. Although the traditional traffic control signals are the ideal solution in this scenario, they have not proven effective due to poor time distribution. Typically, the time intervals allocated to each road are equal …

A Study on the Influence of Cashew and Pawpaw Leaf on Soil Density Treatment of Contaminated Swampy and Clay Soils
Abstract: Soil density is a key parameter in assessing soil health and structure, often employed as a potential index in bioremediation studies. This study investigates the impact of bioremediation treatments using Cashew Leaf (Anacardium occidentale) and Pawpaw Leaf (Carica papaya) on the density of swampy and clay soils over time. The results show that both treatments, in varying quantities, influence the soil's density by reducing the post-contamination density to levels closer …

Quality Sustainability Of Recycled High Density Polyethylene (HDPE)
Abstract: The main way to reduce the generated large amounts of polymer waste is their recycling, their return to the processes of processing and reuse. The main and most commonly used method is mechanical recycling, in which some of the characteristics of the processed material deteriorate. It is known that the properties of the recyclate are most significantly affected by the homogeneity and the degree of aging of the end-of-life plastic …

Optimization of Consolidation Temperature and Time for Self Reinforced High-density Polyethylene Composite
Abstract: Demand for high-density polyethylene (HDPE) for industrial production of domestic and commercial commodities has made it necessary to find ways of improving its mechanical properties. A viable approach towards this is the addition of reinforcements such as glass fibers. However, glass fiber reinforced composites suffer limitations because of reduced recyclability, great weight and difficult to thermo-form. In order to improve properties such as specific strength, stiffness and thermoformability of the …

Density Functional Theory (DFT): Understanding and Quantifying Molecular Structure of 2-D Materials
Abstract: Density Functional Theory (DFT) has emerged as a cornerstone in computational chemistry and materials science, offering a powerful framework for predicting electronic structures and properties of atoms, molecules, and solids. By focusing on electron density rather than wave functions, DFT simplifies the many-body problem through approximations like the local density approximation (LDA) and generalized-gradient approximations (GGAs). The Hohenberg-Kohn theorems establish the theoretical foundation, proving that ground-state properties are uniquely determined …
